getting rid of pass

[David Murmann]

Hi all!

i just had this crazy idea:

instead of

while cond():
pass

write

while cond().

or

try:
import xyz
except ImportError:
pass

compared to

try:
import xyz
except ImportError.

i don't know whether this is syntactically unambiguous or replaces all
uses of pass, but i find it quite nice to read.

also if something like this has been proposed before and rejected, i
apologize for this late-in-the-night idea.

what do you people think?


have a nice day, David.

Viewing statememts as functions of the program state, pass is the identity
function/statement. Many languages have the equivalent. Being explicit is
Python's style. Getting rid of it would gratuitously break code for no
reason other than your esthetic preference.

while x/3.

would become somewhat ambiguous.

I don't. I find it highly unreadable. I really find the pass statement
to be a great idea, and to highly improve readability.

Please don't feel offended, but I think it would be a very bad thing to do.
